Preliminary NTSC progressive scan support. 

The detection is based on a quickly reversed smode1 flag and needs to be done properly.
The timing itself also needs reversing and has only been tested on the VP2 intro video.
(That video now runs without audio / video desync when progressive scan is enabled :) )
